3 ENERGY RECOVERY DRIVE PULSE OUTPUT
3-1 Plasma Panel Energy Loss
When the Sustain, Scan and Data drive pulses are supplied to the plasma panel a lot of energy was lost by
resistance of the electrodes lead and many of switching elements. Because plasma panel has the stray
capacitance and this capacitance makes high level inrush current during the charge and discharge.
This energy loss becomes high temperature from the plasma panel itself.
